The purpose of money is to spend it, just do it in a clever way. Saving it helps when you aren't sure for something bigger.
What bigger are you talking about? There are a lot of ways that you could use the money for the benefit of yourself, something better to do with it. It's better to have a safety money amount that will cover yourself for at least 3 months if you haven't got a job or work. Better to be safe than sorry.
